The 25th annual National Geographic Traveler Photo Contest is under way, and entries will be accepted for another six weeks, until June 30, 2013. First prize winner will receive a 10-day Galapagos expedition for two. National Geographic was once more kind enough to allow me to share some of the early entries with you here, gathered from four categories: Travel Portraits, Outdoor Scenes, Sense of Place, and Spontaneous Moments. Photos and captions by the photographers.
